This solution works for me, i got a Sony Vaio VGN-C140F/B with Core 2 Duo 1.66GHz, so i have the realtek high definition audio sound card in windows Xp works excellent, so when i install mac os x 10.4.6HOTiSO didn't work, so i search for almost all the forum to get a solution so i found it, so this solution works for me so let's go:

You must to check this things before you do something:

1. Your codec is the Realtek ALC262 (vendor id=10EC ; device id=0262).
2. The controller chip you will have to look up. Go into Windows' Device Manager. In Device Manager, go to "System devices". Find "Microsoft UAA Bus Driver For High Definition Audio"and get Properties. Then click the Details tab and get the vendor and device ids, you must have this (vendor id=8086, device id=27D8).
3. When you got this information change to mac os x.
4. First, Backup the AppleHDA.kext and removed it from /System/Library/Extensions/
5. Find the kext AppleAzaliaAudio.kext and edit it:

In Terminal, type:

cd /System/Library/Extensions
sudo pico AppleAzaliaAudio.kext/Contents/Info.plist

then search for IOHDAudioCodecVendorID, when you find it

Find:
<key>IOHDAudioCodecVendorID</key>
<string>0x10ec0880</string>
Change <string>0x10ec0880</string> -- to -- <string>0x10ec0262</string>

For exit pico: press Ctrl + O to save and then Ctrl + X to exit.

6. In Terminal, type:

sudo pico AppleAzaliaAudio.kext/Contents/PlugIns/AppleAzaliaController.kext/Contents/Info.plist

Search for IOPCIPrimaryMatch.

Find:
<key>IOPCIPrimaryMatch</key>
<string>0xNNNN8086</string> (where NNNN are any 4 characters)
Change <string>0xNNNN8086</string> -- to -- <string>0x27d88086</string>
For exit pico: press Ctrl + O to save and then Ctrl + X to exit

7. Repair Peri¡missions using the disk utility in Utilies in the Finder or typing in terminal: sudo diskutil repairpermissions /

8. In Terminal type: sudo chown -R root:wheel AppleAzaliaAudio.kext

9. In Terminal type: sudo chmod -R 755 AppleAzaliaAudio.kext

10. In Termina type: cd /System/Library
sudo rm -rf Extensions.mkext Extensions.kextcache


11. Then if you do this well, reboot and you have SOUND!!!!!!!!!!!!


Of course works for me, please feedback and let me know anything about the solution.

TOPIC UPDATED 22/10/07

Hi guys, i made a change in the step 4, from a user made a suggestion about to mention that the kext AppleHDA.kext, need to be removed from the extensions Folder, so i did the change . If you have any question or comment please contact me.


*****TOPIC UPDATED 18/12/07*****

Hi everybody, i want to share my happiness with all of you, because FINALLY I CAN MADE THE HEADPHONES WORK IT OUT, THANKS TO TARUGA'S APPLE HDA PATCHER VERSION 1.20. Simply follow these instructions and you can hear sound from the headphones and internal speakers:

NOTE: This solution works for me with my laptop mention above. I hope the same results for you.

Forget all the steps mention above and follow these new ones.

1. Simply download the files that i have attached.
2. There will be 2 files: ALC262_codec_dump.txt & AppleHDAPatcherv1.20.app
3. Simply drag & drop the file ALC262_codec_dump.txt to the AppleHDAPatcher application.
4. The program will ask for you password, put it and wait until the programs end.
5. Reboot the system and pray.
6. If everything gots fine, you can check in the icon Sound in System Preferences and you will see in the tab Output headphone built-in & speakers built-in.
7. So you got it. Remember this solution works for me i can't guarantee the same results as mines.

Enjoy!!!!!!

Please let me now any question do you have, if works or don't.

Greetings, and Merry Christmas and a Happy New Year to all of you.

Alfred.

Sorry about the HDD i mean 100GB not 1000GB sorry.

Regards.

1 TB wow funny

That configuration no work with my chipset.

i Have the ALC860 but the input are not recongnized, anybody use the same chip? how can i make work.

OK thanks a ton for these instructions, got me going on my Vaio VGN-TXN15P with the ALC262.

I can get AppleAzaliaAudio.kext to load and then my sound is output through headphone port but not laptop speakers.

I have the same bus, 0x808627d8, Azalia drives the headphones but not the speakers. As soon as I load any version of AppleHDA.kext I get an IOPCI mismatch and lose the sound-trying the HDA that came with 10.4.8 JaS and a 10.4.3 copy but neither will load successfully even though my hardware IDs are correct.


EDIT: Sounds like there is some progress on this front. As of this edit (1-7-07) you get your laptop speakers or the headphone port but not both. But from this post:

http://forum.insanelymac.com/index.php?s=&...st&p=267966

It looks like there is a patcher in the works. I'm hoping that someone a lot smarter than me (Taruga) can sort this 262 chipset out.

I have the ALC262 also, got the sound to work on the laptop speaker.. But when plug in the headphone through the headphone jack, no sounc comming out. Has naybody have this problem? How about going to fix it?

And YES: my headphone is working. When plug in, no sound on the laptop speaker, and no sound to the headphone.

On system: no sound profile
On the device: HD Audio Outplut NO INPUT

What model do you have?

And what ethernet device id and sound device id

I think :
network : 4351 820F104
audio : 0262 104D1500 or 10EC
if it is false tell me where can i find correct device id ?

is it correct?

Hi Alfred, thanks for the work around. unfortunately, my ALC 262 doesn't work with the above mentioned method.

under sys preferences, there's no audio device recognized. under audiomidi app, there's no o/p or i/p devices found.

any other things i can to try? do i need to download another azalia kext to use your method?

thanks.
(ps i'm running 10.4.8 on a fujitsu laptop, C2D, 945 chipset)

sorry guys, i've found out what went wrong. i didn't del the appleHDA.kext. after much reading & searching, finally realized what Alfred meant by backup the appleHDA & place it somewhere else.

KUDOS!!! you guys ROX!!

So, what do you mean by "Work" have sound input or not?
I have a ALC260 and couldn't get sound input work in anyway.

Alfred YOU DA MAN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Thank you so much for the directions above. I have been trying to get sound since thanksgiving! And in 30 minutes I had sound out of my Vaio speakers. No to get the headphone jack / sound out to work ! For external speakers. (movies,music etc.)
Anyone that has gotten sound out to work please HELP..... Thanks

I have ALC262 on my toshiba tecra A8-219 but no headphone sound. itunes sound god with my wav's files maybe need sound on my only one output: headphone!!

Ciao Fà

lol...it seems like I have the opposite of everyone else's problem...After applying this fix I have sound working ONLY on the headphone/stereo out jack, and not on the computer's internal speakers. In system preferences, it simply says "HD Audio Output" under the sound output tab. There's nothing listed for input, and in System Profiler it simply says Intel High Definition Audio: ". For reference, I have JaS 10.4.8 installed on a Sony Vaio VGN-G118TN/S (core solo 1.33 Intel 945GM chipset)

So while Taruga may eventually make a patcher for the ALC262, I doubt it will be soon be cause he has no personal interest in doing so as he doesn't own the chipset. Next week (when I have time) I will try to follow the manual instructions behind his patcher to hopefully mod the AppleHDA.kext. This should be possible: we just don't know where to input the proper audio jack/pinout/port assignments. I will also look into modding AppleAzalia.kext if the AppleHDA attempt fails. I really would love to have speakers, and headphone out plus muting when headphones are plugged in. It should be possible; it will just take some time.

Tecra M7 GMA950 CDuo with 10.4.9 Uphuck 1.3 running Semthex SSE3 8.9.1.

I'm waiting for someone to figure this out too, it would really be nice for it to work properly!

Thnx for you guide, but i'm sorry. i have a question:
This work for ALC260 sound card, i think that the two sound cards are the same, but i;m not sure, please help me... i realy need Line In in my pc hackntosh, for use garageband and others

Hi Camilo, the only way you could see if it work, is trying to do the guide, so i don't now if the line in works, because in my laptop when i try to plug in the headphones it didn't work, so i don't know why, and i'm try to fix but with no succes, i think the kext is not design for that sound card, and only was a compatible way to get sound with that kext, so i¡m working on it, if i have news i let you know, so thanks for the question bye bye.

Greetings

Alfred

Azalia settings for INTEL s5000XVN m/b (ALC262):

IOHDAudioCodecVendorID - 0x10ec0260
IOPCIPrimaryMatch - 0x269A8086

Yep! Its work for me! TNX!

with the same controller and audio card on a fujitsu laptop I still have problems.

I've followed the guide and now i can see a device on the output tab, but still no sound from speakers or headphone.

Any suggestion ?

Thanks

Hi macosse, did you delete the AppleHDA.kext? and did you repair Permissions?, if you done this, maybe you speakers don't work, because in some cases you have configured the sound but, the speakers don't work is a kind of bug, presented in some laptops. Give me more details, of how did you do, step by step?

Greetings.

I've been trying what the guide said to do, and I've got the same problem as macosse had...
Any suggestion ?

Thanks

Did you try the installer in post #27?

I'm currently using MacOS X 10.4.8 kernel (unknown)
Is the kernel version has effect on this problem?
(btw how can I know what version of kernel I'm using of?)

Hey ayrus02, try first deleting the AppleHDA.kext (I recommend you to make a backup first, just put it in another folder, then delete it), do the guide again I´m prettey sure that will work correctly, remember to deleate AppelHDA.kext, if you don´t do this it will not work, if you do it correctly you will have output sound on speakers or headphone (it seems that is just one of then no both, I mean you can have onle on speakers or only on headphone), and you will not get the mic in, but hey!! its a progress, theres some drivers patch for this alc262 cards, but it didn´t work for me, I´m still waiting for it, ciao.

Guys,

I have to say excellent work I now have sound working on my Samsung Q1U! Theres a bit of a sync issue when playing with video but listening to music from itunes works. If I can get that issue resolved i would be in heaven. Finally, does anyone know of a touch screen calibration tool for OSX?

Yes Alfred, I've done everything exactly as you explained. I have a Fujitsu lifebook c1040 and I've now tried with a fresh install (xxx 10.4.10) but still the same result. I've also tried with the easy fix published here but nothing. I'msure to have the same controller and the same Realtek chip of your guide and I've done exactly what you wrote. I do have now an output device in the audio system preferences, but still not working. It's a pity!!Thank you very much for you interest and for your nice howto, though. same card in a lifebook c1040 and a 10.4.10 fresh install. Tried your pkg but still no working audio.

Hey guys,

I followed the intructions, and now I got output option showing up in the settings, and i can turn up and down, but I can't hear anything out of my laptop speakers or if i plug in headphones, etc.

Please help.

This methods works great on my Sony C1Z laptop with ALC262 audio. Took me a while to figure out that I needed to remove the AppleHDA.kext from the extensions folder, but after that final step, I have built in audio working just fine... (no headphone output as expected...)

Can I suggest the first post is edited to say that the AppleHDA should be backed up AND REMOVED from the extensions folder? I'm sure that would help future ALC262 owners.

Big thanks for to the original poster for this fix...

Hi TonyMo, thanks for your comments, and share your experience with us, about this fix. About your suggestion to edit the first post, in a few i did the correction, so thanks again for your suggestions. Later

Greetings
Alfred

I've found a user with the same card (alc262) in a similar laptop, that was able to get it working with azalia audio but only with a 10.4.9 release.
So I've tried myself but still nothing was working. It's really strange.
I've then tried with a different approach; 10.4.10 fresh install and taruga's test kext for alc262 (so no need for azalia and with a patched AppleHDA and ALCInject).
Now headphones are working but not internal speakers. With taruga's test1 kext only headphones are shown in system preferences; with both test2 and test3 also internal speakers are shown in system preferences but only headphones are working .
Hope this will help someone the same problem.
I will keep tring to get internal speakers working.
Thanks again to Alfred for sharing his solution.

I have this audio card, but have not probed the problem down to the id.etc...

but wanted to let you guys know about a great little device I've had for a awhile:

Behringer U-Control UCA202

It's plug'n'play with no drivers [sometimes I've noticed it needs to be plugged in when you power it on for the first time, but then it seems to recognize it from then on after it loads the drivers info into cache].

Optical in and out, along with RCAs. Headphone pre-amp. Bus powered.

For less then $30 dollars shipped, its well worth it.

Does this patch work with all brands of laptop or is it just for your laptop with similar hardware/vendor id? I have a everex brand laptop with alc262 sound card.

Hi,
I tried the above audio jack solution on leopard but it is only partially working
When I select "headphone" as output from the sound in Preferences, sound comes out from both the headphone and the speaker. In contrast there is no sound in neither output when "speakers" is selected.

Any help?

Hi bubugugu, the solution is only works for Tiger, and i hadn't tested in Leopard so try another solution for your sound card. Greeting

Happy New Year.

Alfred, you're my saviour! Thank you for the codec dump file and your solution, works great on Leopard

my vaio TX751P I had everything going but it was an SSE2, so was limited to only booting on battery... got a TX850P and with its 950GMA got everything, except sound... today, sound is WORKING!!! thanks everybody on the site for everything, I now have a full functional vaioBook pro...

so sounds work both on speakers and headphones now on leopard? or no?

i´m glad, i was searching for a few hours how to solve this trouble... now i just want to tank you man, i has used yours steps and downloaded the patcher, now the audio go on Leopard!!!
Thanks again!!!

You are a champ! THANKS! - working on my toshiba r20 tablet


EDIT:
P.S. IMPORTANT!!! - Leopard saw the audio and i could change the volumes, but no sound came out until i booted to my XP tablet and un-muted the sound in there...once it was turned on again - all the way up, i rebooted leopard and it worked!

...weird that it remembers its last state/cannot change or overwrite its own...

This is the first solution that even has my headphones working for Leopard on my Sony Vaio TZ150...sort of. For the Internal Speaker setings it recognizes the headphones, and I get sound, but sound continues to come of of the internal speakers as well. There is no sound when choosing the headphone outputs from either, also no controls for the headphones.

Has anyone else seen this or come up with a solution yet?

I have tha same situation.
Has anyone come up with a solution?
